FoxAlky Posted March 15 Share Posted March 15 I just upgraded my gpu in hp zbook 15 g2 from quadro k2100m to quadro m2200. I changed whole cooling system to the new one (cause old was damaged) and used honeywell ptm 7950, and cpu is cooling down just fine but the gpu on the stock temp limit easly can hit 90 degress, after undervolting and lowering the temp limit, gpu hits 86 and when starts hitting 87 it is dropping clock, please help Link to comment Share on other sites More sharing options...
gluon Posted Wednesday at 07:50 PM Share Posted Wednesday at 07:50 PM I looked into further GPU upgrade options for this specific laptop model. Here's some things I've learned. ZBook 15 G2 GPUs have a hard power-limit of 75W. This plateaus the performance of cards with larger TPD. All Pascal and Turing cards are supported. No BIOS whitelists. Any supported card with any vBIOS should work out of the box. Hybrid Graphics need to be enabled for anything above Kepler. Ampere cards and newer require Above 4G Decoding. The G2 BIOS does not support it. Also, HP BIOS's are said to have RSA checksum protection. MXM-A is the default form factor. B-type cards can be installed via hardware mod. In such case, the heatsink should also be upgraded to the 17 G2 model. The bigger heatsink has a different temperature sensor, suitable for MXM-B. The native heatsink only works properly with A-type cards. Mismatch causes constant fan spin. With these caveats in mind, the Turing gen offers some alternatives. - T2000 Mobile. 4gb, MXM-A, 60W power draw. An easy update from the M2200. Performs at around GTX 1650. - RTX 2060 Mobile. 6gb, MXM-B, TPD > 80% (max draw 80-90W). Best performance/power balance. - RTX 6000 Mobile. 24gb, MXM-B. Should boot up and work, with a third(!) of its TPD. On the AMD side, Polaris cards are confirmed to work. The ones that stand out are the RX 550 (4gb, MXM-A) and RX 580X (8gb, MXM-B). Hope this helps my fellow ZBook users should they need further upgrades. If anyone gets into testing, do post your results!
